Detailed explanation-1: -All cells process energy and nutrients. All cells use changes in its DNA to adapt to its environment. All cells contain a cytoplasm surrounded by a plasma membrane, DNA in the form of chromosomes and ribosomes.
Detailed explanation-2: -Cells require chemical energy for three general types of tasks: to drive metabolic reactions that would not occur automatically; to transport needed substances across membranes; and to do mechanical work, such as moving muscles.
Detailed explanation-3: -All living organisms share several key properties such as order, sensitivity or response to stimuli, reproduction, adaptation, growth and development, regulation, homeostasis, and energy processing.
Detailed explanation-4: -The cell provides support and structure to the body. It facilitates growth by mitosis. It helps in reproduction. Provides energy and allows the transport of substances.
Detailed explanation-5: -ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus. Because of the presence of unstable, high-energy bonds in ATP, it is readily hydrolyzed in reactions to release a large amount of energy.
